[regression] ColorPalette colors don't match up with their borders well when used with other widgets.

While using the DropDownButton, TooltipDialog, and ColorPalette widgets together, some of the focus borders, which are supposed to go around the colors, don't fit very well. As you go to the right, they become less and less aligned.

Ouch, thanks for the test case. Looks like the padding: 8px setting on the dijitTooltipContainer causes the rendering problem, presumably due to some IE bug. Although a plain <div style="padding: 8px"> wrapper around a ColorPalette works.
